在我的應用程序中,每次用戶試圖分享帖子時,都想顯示twitter登錄。Android中的Twitter身份驗證
我不想在共享首選項中保存Twitter憑據,但是當我第二次嘗試共享帖子時,它沒有顯示登錄字段。
任何人都可以找出問題嗎?

我最好的猜測是,當您共享的第一個鳴叫你的應用程序中獲得的OAuth訪問令牌仍然是有效的,當你共享第二鳴叫(即尚未過期) 。我對OAuth沒有太多的工作,但我建議你看看如何「調整」令牌的到期時間,以便在共享推文後立即過期。請注意,如果您的OAuth庫在封面下使用刷新令牌,則這可能不起作用。 – curioustechizen 2012-01-31 07:24:04
